TAKE-UP DEVICE.

Application filed January 16, 1915.

To all whom it may concern:

Be it known that I, MAURICE Gnnnnnnno, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new .and usefulImprovements in Take-Up Devices, of which the following is aspecification.

My invention relates to a take-up device for window shades, among otheruses there for, and in its use in connection with a window shade,preventing'in elevating the shade the drawing cord thereof wrappingaround the shade roller or in the drawing of the shade in a downwarddirection of the parting of the upper end of the shade from the rollerthereof; and in such connection my present invention relates to thetake-up device to maintain in such use the guide-wires along which theshade is moved up and down in a taut condition for reliable working ofthe shade and Without creating in the handling ragged edges of the same.

The nature and scope of my invention will be more fully understood fromthe following description taken in connection with the accompanyingdrawings, forming part hereof, in which- Figure 1, is a vertical centralsectional view through a take-up device embodying the features of myinvention, showing the detail arrangement of said device; and Fig. 2, isa front elevational view of a window frame and shade with itsguide-wires, showing one application of the said take-up device thereto.

Referring to the drawings a, is the window-frame and m the bottom sillor ledge. The shade 2), is fitted to an ordinary spring controlledroller 0, the journals 0, of which are detachably fitted tol'n'acket-holders d, provided respectively with the usual eye in one anda notch in the other. The bracketholders are each provided with an eye(Z The shade at the bottom is looped at 6 and in the loop is inserted astrip of wood or other material. Both ends of the strip 0 are providedwith a loop 25 From the eyes 45 guide-wires (Z extend in a downwarddirection. At the bottom, each guide-wire (Z is fitted into a take-updevice 0, consisting Specification of Letters Patent.

of a channeled nut 6 having a threaded interior surface and also havingan eye o in the rear flanged wall 6 and into which the end of the wire(Z is seated and said nut arranged to take up slack in said wire by theturning of the nut on the shank or spindle a The shank or spindle (1 isprovided with a base-plate 6 secured to the windowframe a, as clearlyshown in Fig. 2. The spindle 6*, also is provided with a jam-nut e, totighten the channeled nut 6 when a guide-wire passing through a loop 6of the bottom-strip of the shade 7), is brought into a taut conditionwith said channeled nut 0 to maintain the same in such a condition as topermit of the shifting of the shade in up and down directions withoutcreating ragged edges of the shade or parting of the same at the upperend from the roller (1.

The foregoing explained arrangen'ient of a window shade thereby insuresuniform action without the necessity of special care in the handling ofthe same as it matters not how carelessly the shade may be handled, itcannot become ragged along its edges or can the upper end of the shadepart from its roller so long as the guide-wires on both sides of theshade are maintained in a taut condition by means of the take-up deviceof my said invention.

Having thus described the nature and objects of my invention, what Iclaim as new and desire to secure by Letters Patent is A take-up device,consisting of a baseplate having a threaded shank, a channelednutthreaded to the shank and having an eye in the rear flanged wall andinto which the end of a wire is seated, said nut arranged to take-upslack in the wire by the turning of the channeled-nut on said shank anda lock-nut fitted to said shank and adapted to frictionally bear againstthe front wall of said channeled-nut to prevent slackening of said wire.

In witness whereof, I have hereunto set my signature in the presence oftwo subscribing witnesses.

MAURICE GREENBERG.
